All-radiation environment calibration device for photoelectric daylight meter

Abstract

The calibration device for photoelectric sunshine meters relates to the technical field of meteorological instrument detection, and solves the problem that the existing sunshine meters cannot work continuously outdoors for a long time, and the test data is discontinuous and the test time is long, resulting in low calibration efficiency; and the existing Most indoor calibration devices do not simulate the radiation environment, which reduces the measurement accuracy of the pyranometer, including fixed brackets, solar simulators, solar-terrestrial motion simulation institutions, and radiation environment simulation rooms. The solar simulator is fastened on the fixed bracket, and the collimated light beam emitted is reflected by the plane mirror to the photoelectric helium meter to be tested, and the helium meter to be tested is clamped on the high-precision optical rotating platform by the fixture to realize the adjustment of the altitude angle and the azimuth angle , to simulate different irradiation angles of the sun; through the radiation environment simulation room, simulate the influence of different air temperature, humidity and air quality on the radiation effect under the solar radiation environment. The invention reduces the workload of operators and improves the calibration efficiency.

Description

technical field [0001] The invention relates to the technical field of meteorological instrument detection, in particular to a full-radiation environment calibration device for a photoelectric sunshine meter. Background technique [0002] The photoelectric sunshine meter is a meteorological instrument that records the sunshine hours. Due to its characteristics of low cost, fast response, good safety and reliability, low cost and maintenance cost, it is now widely used in solar energy resource measurement, meteorological radiation observation and other fields. [0003] The calibration test of the photoelectric sunshine meter is the key link to realize the high-precision measurement of sunshine hours. At present, under the minimum requirements, the operator uses the standard pyranometer and the insolation meter to be calibrated outdoors for comparison and measurement when performing calibration operations for the photoelectric daylight meter. When the weather is bad, the out...
